Joneses from all over Wales and as far afield as the United States and Australia are heading to Cardiff tonight in an attempt to break the world record for the biggest get-together of people with the same surname.

Over 1,600 Joneses are expected to make up the audience at the 'Jones Jones Jones' show in the Wales Millennium Centre, which will smash the current record, set in 2004 by 583 Norbergs in Sweden.

With Jones the most common surname in Wales and the second-most common name in Britain, the average attendance at a Wales-England rugby clash is just as likely to yield a record-breaking number of Joneses, but the organisers of tonight's event are taking it very seriously, with a host of famous Joneses taking to the stage to perform at the record-breaking attempt.

Among them will be former Bond girl, model and pop singer Grace Jones, opera singers Dame Gwyneth Jones and Gwyn Hughes Jones, and West End star John Owen-Jones.

A large number of Joneses are expected from Blaenau Ffestiniog in Snowdonia, which boasts the highest proportion of Joneses in the UK.

Blue Peter presenter Gethin Jones and former S4C presenter Gwenllian Jones will co-host the evening, which will be broadcast on the Welsh channel S4C at a later date. Officials from Guinness World Records will be on hand to verify the record.
